Hi,<br>
<br>
When need to add a new wms layer is preferrable to avoid to use the
cache but, instead, do a new getcapabilities request and list the
layers as resulted by the xml response .<br>
Also I guess a the time lost is not only the request/response time,
but also the parsing time of the response.<br>
A cache do not help on this.<br>
<br>
The question is strictly referred to the open project time.<br>
<br>
Also as reported yesterday.<br>
If I check the option "Ignore GetMap/GetTitle URI reported in
capabilities"<br>
where qgis store the getmap/getfeatureinfo/getlegendgraphics urls ?<br>
They seem to be no store no where.<br>
So it can only use the unique url stored in the datasource tag.<br>
These mean that qgis assume the url are the same for all three
requests.<br>
This could be reasonable.<br>
But in this situation, QGIS do however a getcapabilities request.<br>
<br>
I don't understand this.<br>
<br>
So my dubt is that the getcapabilites request at startup of a
project is really unuseful.<br>
If this is the question perhaps also a cache would be only a
redundant overstructure .<br>

<div>Hi all<br>
<br>
</div>
Why not "just" caching the getCapabilities response for the
current QGIS session ? This way, if you have 100 layers
coming from the same WMS server, only one request will be
made when opening the project and the response will be
stored in cache and used for other layers.<br>
<br>

Please open a feature request in the QGIS hub and attach your
project for further tests.<br>

It is a project for qgis 2.12 using only wms layers.<br>
